Southampton v Manchester Utd, Premier League: St Mary's Stadium, Today, 3.00 pm
Luke Shaw "has to improve" to get into Manchester United's starting line-up, but Jose Mourinho is staying patient as the left-back returns from his latest injury lay-off.
After shining for Southampton and playing for England at the World Cup, United made the full back the most expensive teenager in history three years ago.
Shaw has managed just 48 appearances for United since the move due to a mixture of form and fitness issues, most pertinently the double leg break that brought his second season at the club to an abrupt halt.
The 22-year-old returned to the fold last term but Mourinho publicly questioned his attitude, application and football intelligence during a comeback campaign ended in late April by foot ligament damage.
"He has to work, just that," Mourinho said ahead of today's trip to the left back's former club Southampton.
"You saw the game, you saw the same as I see, so are you asking if he plays tomorrow? No, he is not playing tomorrow. He has to work. He has to improve.
"Look, he doesn't play for six months. I am not expecting him to arrive on Wednesday and to be man of the match or to be running up and down for 45 minutes.
"You have other players that in this moment who are not starting matches and their managers just say 'they're not in the best conditions'. And we're speaking about some of the best players of the Premier League.
"I heard last week the Chelsea manager saying that, I heard Arsenal manager said that. The players are not in their ideas, in their analysis, they're not in the best form after injuries and long time without playing.
"Luke had surgery and a long time without playing football. I cannot expect him to be back and to be strong, strong, strong in his work."
Shaw was not alone in finding himself under scrutiny during Mourinho's first season.
Anthony Martial got under the United manager's skin at times, but the forward has returned from the summer with a fresh mentality.
"He's improving a lot," Mourinho said. "Not just on his will, his desire to do it, but being effective on that. Very good. "
